摘　　要：煤矿井下环境相比于地面普遍存在潮湿、粉尘污染和视野差等情况,但井下设备又不能全部开到地面进行加油,因此开发一种新型的射流阀已满足井下设备的加油过程。该阀普遍具有结构简单、体积小、成本低的特点,但是射流阀本身的特性确无法通过设计计算得到,该文主要对锚杆钻车中使用的加油射流阀进行分析,通过设计不同的流量和面积比计算射流阀的特性,为后续加油射流阀应用于不同的场合提供相关计算参考和结构完善。The coal mine environment compared to the ground wet dust pollution and poor vision, but underground equipment and I could not open all to the ground to go, so the development of a new type of jet valve has meet the refueling process of downhole equipment The valve is generally has a simple structure The characteristics of small volume of low cost, but the nature of the jet valve itself it does not obtain in design and calculation, this article mainly the gas used in the jumbo jet valve of anchor bolt is analyzed, through the design of different flow rate and area than calculating the properties of the jet valve, cheer for subsequent jet valve used in different occasions to provide a reference for calculation and perfect structure.
